[0002] In today's digital age, wireless earphones have become an indispensable part of people's daily lives due to their convenience and excellent audio experience. As an important accessory for wireless earphones, the earphone box not only provides the functions of storing and protecting the earphones, but also has a crucial impact on the user experience in terms of the rationality and innovation of its design. Among them, the earphone box hinge, as a key component connecting the box body and the box cover, plays an important role in the overall performance and user-friendliness appearance of the earphone box.

[0003] Referring to the utility model patent with the publication number CN214901254U, a multifunctional wireless earphone box is disclosed, which includes a box body and a box cover hinged or movably connected to the box body. A storage cavity for storing wireless earphones is provided inside the box body, and a magnetic adsorption layer or an adhesive layer for connecting to a mobile phone is provided on one side of the box body. The multifunctional wireless earphone box realizes the hinge connection between the box body and the box cover through a hinge block. When the box cover is opened, the hinge block can keep the box cover connected to the box body. However, there is no corresponding structure on the hinge block to keep the relative position between the box cover and the box body fixed, resulting in the box cover being prone to swing when the user takes out the earphones, affecting the user's operation and reducing the user experience.

[0004] Therefore, it is necessary to provide a technical solution to solve the above problems. Summary of the Utility Model

[0005] The utility model is developed and improved in view of the problems existing in the existing wireless earphone boxes, aiming to design a hinge and a corresponding earphone, so that the position of the box cover relative to the box body can be relatively locked after the box cover is opened, and at the same time the box cover can be closed relatively easily, thereby improving the user experience.

[0006] To achieve the above object, the utility model provides a hinge, which includes a fixed seat, a rotating piece, a support and an elastic member;

[0007] The rotating piece is hinged to the fixed seat, and the rotating piece rotates relative to the fixed seat around the rotation axis; a connecting shaft is arranged outside the rotation axis of the rotating piece; a limiting structure is arranged on the fixed seat and / or the rotating piece, and the limiting structure is used to limit the rotation range of the rotating piece relative to the fixed seat;

[0008] The support is hinged to the fixed seat;

[0040] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0041] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element at the same time; when an element is referred to as "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0042] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality" means two or more, unless otherwise specifically defined.

[0043] In the description of the embodiments of the present utility model, it should be understood that the orientation or positional relationship indicated by "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the embodiments of the present utility model and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model.

[0044] In order to more clearly illustrate the technical solution of the present utility model, a preferred embodiment is provided below. Specifically, refer to Figures 1 to 11 , a hinge, comprising a fixed seat 1, a rotating piece 2, a support 3 and an elastic member 4;

[0045] The rotating piece 2 is hinged to the fixed seat 1, and the rotating piece 2 rotates relative to the fixed seat 1 with the rotation axis a as the center; a connecting shaft 21 is arranged outside the rotation axis a of the rotating piece 2; a limiting structure is arranged on the fixed seat 1 and / or the rotating piece 2, and the limiting structure is used to limit the rotation range of the rotating piece 2 relative to the fixed seat 1;

[0046] The support 3 is hinged to the fixed seat 1;

[0047] Both ends of the elastic member 4 are respectively connected to the support 3 and the connecting shaft 21;

[0048] Wherein, the rotating piece 2 can rotate relative to the fixed seat 1 until the elastic force direction f received by the connecting shaft 21 points to the rotation axis a.

[0049] Through reasonable adjustment of the structure of the present utility model, during the process of changing the elastic force direction f received by the connecting shaft 21, the movement trend of the rotating piece 2 generated by the elastic force acts is switched between the clockwise direction and the counterclockwise direction. For specific reference, see Figure 9 When the elastic force direction f of the connecting shaft 21 points above the rotation axis a, the rotating piece 2 will have a tendency to rotate counterclockwise under the action of the elastic force. For reference, see Figure 7 When the elastic force direction f of the connecting shaft 21 points below the rotation axis a, the rotating piece 2 will have a tendency to rotate clockwise under the action of the elastic force; thus, after the user pushes the rotating piece 2 to rotate a certain angle, the rotating piece 2 will automatically pop out or bounce back inward under the action of the elastic force, making the opening and closing operation of the hinge easier and improving the user experience.

[0050] The hinge 300 involved in the present utility model is usually applied to a headphone case. The headphone case further includes a case body 100 and a case cover 200, wherein:

[0051] The case body 100 is fixedly connected to the fixed seat 1;

[0052] The case body 100 is mounted on the rotating piece 2.

[0053] It should be understood that when the hinge involved in the present utility model is in the open and closed states, the rotating piece 2 will be subjected to the elastic force applied by the elastic member 4, and with the cooperation of the limiting structure and the elastic force, a relative locking effect can be generated between the rotating piece 2 and the fixed seat 1; when the headphone case using this hinge is in use, it can ensure that the case cover 200 can be relatively fixed to the case body 100 whether in the open or closed state, facilitating the user to take and place the headphones and improving the user experience.

[0054] In this embodiment, when the included angle between the rotating piece 2 and the fixed seat 1 is 135° - 145°, the direction f of the elastic force received by the connecting shaft 21 points to the rotation axis a. It should be understood that the angle at which the lid 200 of the earphone case can rotate relative to the case body 100 is usually 90° to 120°. With the above design, not only is the angle required to push and rotate the lid 200 relatively moderate when the user opens and closes the earphone case, making the operation more convenient, but also the locking effect is better. Taking the above included angle set to 140° as an example, when the lid 200 is not rotated to make the included angle between the rotating piece 2 and the fixed seat 1 greater than 140°, the lid 200 will automatically rebound to the closed state, or when the lid 200 is not rotated to make the included angle between the rotating piece 2 and the fixed seat 1 less than 140°, the lid 200 will automatically rebound to the fully open state. In this way, the risk of the lid 200 being accidentally opened or closed can be reduced.

[0055] In this embodiment, the elastic member 4 includes a support rod 41 and a spring 42. One end of the support rod 41 is hinged to the connecting shaft 21, and the other end passes through the support 3. The spring 42 is sleeved on the support rod 41, with one end in contact with the support 3 and the other end in contact with the support rod 41. With the above design, the overall structure of the elastic member 4 is simplified, the installation is more convenient, and the elastic force can be stably applied to the connecting shaft 21 to ensure the smooth operation of the lid 200.

[0056] In this embodiment, a receiving groove 11 is formed in the middle of the fixed seat 1, and arc guide blocks 12 extend from both sides of the receiving groove 11; a connecting portion 22 is provided at one end of the rotating piece 2, and arc guide grooves 23 adapted to the arc guide blocks 12 are provided at both ends of the connecting portion 22; the connecting portion 22 is disposed in the receiving groove 11, and the arc guide blocks 12 are inserted into the corresponding arc guide grooves 23. With the above design, the connection between the rotating piece 2 and the fixed seat 1 can be made more stable, and the rotation of the rotating piece 2 can be made more smooth.

[0057] As another preferred solution, a groove and circular holes formed by opening outward from both sides of the groove are provided in the middle of the fixed seat; a connecting rotating shaft is provided at one end of the rotating piece, and the connecting rotating shaft is disposed in the groove and both ends are inserted into the corresponding circular holes. The above design is a conventional hinge method and will not be elaborated here.

[0058] In this embodiment, the limiting structure includes a limiting block 13 provided on the arc guide block 12 and a pin 24 provided on the rotating piece 2. The limiting block 13 is disposed in the arc guide groove 23, and the end of the pin 24 is disposed in the arc guide groove 23, and its position corresponds to the position of the limiting block 13. In actual application, the rotating piece 2 can rotate clockwise or counterclockwise. After rotating until the pin 24 contacts the limiting block 13, the rotating piece 2 cannot continue to rotate in the original direction, thereby achieving the limiting effect.

[0059] As another preferred solution, the limiting structure includes a straight portion 14 provided at one end of the arc guide block 12. One end of the arc guide block 12 penetrates through the connecting portion 22, and the straight portion 14 is provided outside the arc guide groove 23. In actual application, after the rotating piece 2 rotates a certain angle clockwise or counterclockwise, the straight portion 14 will move to the end of the arc guide groove 23. Since the shapes of the straight portion 14 and the arc guide groove 23 do not match, the rotating piece 2 cannot continue to rotate in the original direction, thereby achieving the limiting effect.

[0060] In this embodiment, a plurality of first mounting holes 15 are formed in the fixed seat 1. In actual application, the cooperation of the first mounting holes 15 with structures such as buckles or screws on the box body 100 is used to realize the fixed connection between the box body 100 and the fixed seat 1.

[0061] In this embodiment, a plurality of second mounting holes 25 are installed on the rotating piece 2. In actual application, the cooperation of the second mounting holes 25 with structures such as buckles or screws on the box cover 200 is used to realize the fixed connection between the box cover 200 and the rotating piece 2.

[0062] The above are only the preferred embodiments of the present invention, and its structure is not limited to the shapes listed above. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
